Description
a)50〜99重量パーセントの少なくとも1つのポリフッ化ビニリデン(PVDF)ポリマーまたはコポリマーと、
b)1〜50重量パーセントの少なくとも1つのアクリルポリマーと
を含む均質なポリマーブレンドを含む耐苛性膜に関する。
膜ドープを、清浄なガラス板に注ぎ、ドローダウンスクエア(drawn−down square)によりドローダウンした。湿潤フィルム厚さは5ミル〜20ミルであった。湿潤フィルムを、高湿(65℃の水浴より上の周囲蒸気)に30秒〜2分間曝露した。湿度曝露後、ガラス板を温水浴に浸して、転相を完了し、膜を硬化した。膜形成が即時になされ、形成された膜は、自然にガラス板から持ち上がった。
膜片(約20mm×50mm)を切断し、瓶に入れた。10重量パーセントの水酸化ナトリウムの水溶液を各瓶に加えた。瓶のキャップを締め、振とうして(攪拌でなく)周囲温度で静置した。試料を数日毎に目視でチェックした。2週間後、膜を取り出し、脱イオン水で濯ぎ、次にイソプロパノールに短く浸し、空気乾燥させた。乾燥した膜試料を、Hunter Labscan XE色度計で色の変化を分析した。
